It is well known that the more highly volatile portions of the liquidfuel employed tend therewith and for convenience in Inanufac to vaporizein the "supply tank, and'heretofore this vapor has passed off and, beendissipated anclilost." -My invention contemplates the utilization' ofthis volatile portion I trated, a pipe.. or,tube 34ais connected at onecustomarily surrounding the supply opem V endby means;o:f the nipple 3V5witlfthe ftiel T a Suction of: t e;engine exerted'tlnnugh? the intakemanifold di twsdheivaporsrins th top of; the} fuel tank; through-theopening 3.9. into. the? plp534 by] which; they: are, ,delivere'dh tinto-ithe Etuel; mixture-passagesjustaabove': thev carbureter-"Thesefvapors together ithnthe vapors; and'vuhvapqrizedifuel:,bldlivered from the arbnreter'f pass-1tliroughttheudpenings 24.-in the homogenizer and after beingmaltaerna lv'jthrawns from onenwal-ll:to thQlOtllGI' "of the duel V passagewthnough; wthe liomogenizer aredelivered? into a the 1 intake? inani' itdld 8.
